I got this one and have been quite happy with it. Because it is not magnetic, I can use my standard trip on it without issues (the cyclocomputer is a cadence one which fits to the rear wheel and non-magnetic trainers won't interfere with it). I added in the front wheel support as well which works really well.

It is amazingly quiet - that is something that has surprised me. the resistance is 'odd' in that it just seems to work it out and the faster you go the harder the resistance, if it is too much, I just drop down a gear which works really well. I can get a really good work out from it. But it does not come with a computer etc, I just use the bike's one for that. Adding in the computer adds way too much to the cost £150 at the moment I think!
